Description

Technical Field

[0001] This utility model relates to the field of paper bag manufacturing technology, and in particular to a mold for pasting the bottom of paper bags. Background Technology

[0002] Paper bags are bags made primarily of paper and are widely used for holding items such as shopping bags, gift bags, and food bags. They are not only practical household items but also an environmentally friendly choice. As people's environmental awareness continues to increase, the practice of using paper bags instead of plastic bags is becoming increasingly popular. A paper bag bottom gluing machine is a device that glues the bottom of manufactured paper bags. Usually, an unsealed paper bag is first cut out, then an unfolding mechanism is inserted into the bottom of the paper bag and unfolds the two sides of the paper bag. Finally, the unfolded paper bag is glued. However, most existing unfolding mechanisms are fixed and cannot be adjusted. They can only unfold and support paper bags of a single size, reducing the applicability of the unfolding mechanism. This means that unfolding mechanisms of corresponding sizes need to be replaced for paper bags of different sizes, making it difficult to quickly adapt to the market's production needs for paper bags of diverse specifications. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a die for forming paper bags.

[0004] To achieve the above objectives, the present invention provides a die for forming paper bags, comprising a frame, a conveyor belt driven to the frame, a support member disposed on the frame, and a drive cylinder driven to the support member. The drive cylinder is provided in multiple ways, arranged around the circumference of the frame, with adjacent drive cylinders spaced apart. The support member is provided in multiple ways, arranged in a polygonal shape.

[0005] Preferably, the central axis of the driving cylinder is perpendicular to the central axis of the support member, the support member extends away from the driving cylinder, and a suction cup is provided at the end of the support member away from the driving cylinder.

[0006] Preferably, the frame includes longitudinal beams, crossbeams connected to the longitudinal beams, and a base disposed on the crossbeams. The longitudinal beams and crossbeams are arranged perpendicularly, and the crossbeams are provided with support clamps. The support clamps are clamped and sleeved in the middle of the base.

[0007] Preferably, the conveyor belt body is provided with a connecting block, and the connecting block is connected to the longitudinal beam.

[0008] Preferably, the conveyor belt body is made of PVC or PU material.

[0009] The beneficial effects of this utility model are: by driving multiple support components to move through multiple drive cylinders, the spacing between the multiple support components can be adjusted in a targeted manner, which can quickly adapt to the market's production needs for paper bags with diverse specifications and improve the versatility and compatibility of the work.

[0014] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] like Figures 1 to 2 As shown, the present invention provides a die for forming paper bags and pasting the bottom, comprising a frame 1, a conveyor belt 2 drivenly connected to the frame 1, a support member 3 disposed on the frame 1, and a drive cylinder 4 drivenly connected to the support member 3. The drive cylinder 4 is multiple, arranged around the circumference of the frame 1, with adjacent drive cylinders 4 spaced apart. The support member 3 is also multiple, arranged in a polygonal shape.

[0017] During operation, the cut, unsealed paper bags are first inserted into multiple support members 3 by an external working mechanism. Since multiple drive cylinders 4 are arranged around the circumference of the frame 1, and adjacent drive cylinders 4 are spaced apart, the multiple drive cylinders 4 drive the multiple support members 3 to adaptably extend and retract in the volume space, so that the multiple support members 3 can be arranged into a polygonal shape. Preferably, there are four drive cylinders 4 and four support members 3. The four support members 3 can be arranged into a rectangle, square, or other polygonal shape, so as to better adjust the distance between the multiple support members 3 according to the actual work needs, effectively unfold and support paper bags of different sizes, so that the paper bags are completely flattened, providing stable working convenience for subsequent bottom sealing work. Then, the conveyor belt 2 drives the multiple support members 3 to move through the frame 1, thereby moving the paper bags to the corresponding workstations for processing. This invention uses multiple drive cylinders 4 to drive multiple support members 3 to move, and adjusts the spacing between the multiple support members 3 in a targeted manner, so as to quickly adapt to the market's production needs for paper bags with diverse specifications and improve the versatility and compatibility of the work.

[0018] In this embodiment, the central axis of the driving cylinder 4 is perpendicular to the central axis of the support member 3. The support member 3 extends away from the driving cylinder 4, and a suction cup 5 is provided at the end of the support member 3 away from the driving cylinder 4. Specifically, the central axis of the driving cylinder 4 is perpendicular to the central axis of the support member 3, so that the support member 3 extends upward in the direction away from the driving cylinder 4. The support member 3 moves back and forth and extends and retracts freely by being driven by the driving cylinder 4, thereby pushing the paper bag to fully unfold. The suction cup 5 is provided at the end of the support member 3 away from the driving cylinder 4, and the suction force of the suction cup 5 is used to adhere and fix the short sides of the paper bag, ensuring the efficient operation of the paper bag bottom sealing process.

[0019] The frame 1 in this embodiment includes a longitudinal beam 11, a transverse beam 12 connected to the longitudinal beam 11, and a base 13 disposed on the transverse beam 12. The longitudinal beam 11 and the transverse beam 12 are arranged perpendicularly. The transverse beam 12 is provided with a support clamping seat 14, which clamps and sleeves the middle part of the base 13. Specifically, the transverse beam 12 is disposed above the longitudinal beam 11, and the longitudinal beam 11 and the transverse beam 12 are arranged perpendicularly to each other in a cross shape, resulting in high structural stability. The transverse beam 12 is stably clamped and sleeved in the middle part of the base 13 by the support clamping seat 14, effectively fixing the position of the base 13 on the transverse beam 12, thereby improving the overall structural strength of the frame 1, so that the four drive cylinders 4 can be stably arranged around the circumference of the base 13, ensuring stable and reliable operation.

[0020] In this embodiment, the conveyor belt 2 is equipped with a connecting block 21, which is connected to the longitudinal beam 11. Specifically, the conveyor belt 2 is connected to the longitudinal beam 11 through the connecting block 21, thereby driving the frame 1 to move as a whole, resulting in a compact structure and reasonable design.

[0021] The conveyor belt 2 in this embodiment is made of PVC or PU material. Specifically, the conveyor belt 2 made of PVC material has the advantages of moderate softness and hardness, acid and alkali resistance, low noise, and easy cleaning; the conveyor belt 2 made of PVC material also has the advantages of high wear resistance, grease resistance, good elasticity, and food grade, thus extending its service life.
